It has a six inch dial and is 3.5 inches deep.It has been running in my bathroom for about ten years.The regulator is set to F but it has always lost time a bit.It will need axpert attention.The chrome plated case is in excellent condition for it's age,apart from a small dent near the hinge.See photographs.It is heavy.2.3 kg plus all the packing so international postage will be very expensive.It opens and closes as well as the day it was made because it is a good quality piece.The original brass key comes with it.
